To all ,whom it/may concern.

. Be it known that I, CHARLESv A,.F osTER, a citizen of the UnitedStates, residlng at Portland, in the county of Multnomah and State'` ofOregon, have invented a new and useful Culvert, of which the followingis a specification.

My invention relates to ,culvert constructions and has for its objectthe provision of an abutment adapted to be secured to the intake end ofa culvert to prevent the dirt around the mouth of the culvert from being-v washed away by the action Vof the water which flows through theculvert. 4

Referring to the accompanying drawings, Figure 1 is a. perspective viewshowing a culvert section and the two sections of my new formofabutment, which are adapted ytofit snugly around the culvert section,the parts being in this figure shown disassembled, Fig. `2 shows theparts of Fig. 1 assembled in operative relation, F ig. 3 is a viewshowing a different form of culvert 4section and a correspondinglymodified abutment plate to be secured thereto, the figure showing theparts disassembled, and Fig. 4 is a view showing the parts of Fig. 3assembled in operative relation.

v is substantially circular.- When the culvert is* constructed ofcorrugated sheet metal, as

In its preferred form my novel form of abutment comprises a pair ofcomplementary plates 1 and 2 constructed of corrugated sheet metal.These plates are recessed at 3 and 4, respectively, the preciseconfiguration of the recesses depending on the shape of the culvert-towhich the abutment is attached.

-In Figs. l and 2, the abutment is shown in when the plates 1 and 2 arebrought together the opening formed by the recesses 3 and 4 itpreferably will be, the size of theopening formed by the recesses Band 4is such that the abutment plates snugly fit into one of the corrugationsof the culvert. This is shown inthe assembly view of Fig. 2. The platesv1 and 2 are provided with lateral anges 6 and 7. When the plates areassembled these lateral anges 6 and 7 abut c against each other, asshown in Figs; 2 and 4.

, Suitable fastening devices 8, such as bolts or rivets, pass'throughthe flanges 6 andl 7 and firmly hold the abutment plates together on theculvert.

Specification of Letters Patent. Application led December 19, 1910.Serial No. 598,259.

' In Figs. 3 anu 4 the abutment is-shown' in connection with a culverthaving a` fiat bottom 9 and an arched upper piece 10. In this case therecesses 3 and 4 of the abutment .are of such configuration that whenthel abutment plates are secured in place on the culvert the platessnugly embrace the culvert section.

It will be seen from the above description that the lateral abuttingflanges' afford simple and effective means for securely hold! ing theplates in position on the culvert. Although I have herein shown theabutment as constructed of two complementary plates, it is obvious thatthe number of such .plates may be varied. For instance, 'in case ofabutmentsv of .large dimensions, it may be that more than two plateswonld be required to build up the abutment economically.

Patented Juiy 11, 1911.`

However, for ordinary culverts, a pairv of l complementary plates will.be sulicient to make up the abutment.

kHaving thus described my invention what I claim as new and desiretosecure by Letters Patent of the United States is:

1. The combination with a culvert, of an` abutment therefor,saidabutment comprising a plurality of complementary plates constructedto fit aroundthe `body of theculvert, the contiguous edges of saidplates being provided with lateral flanges which extend at right anglesto the body of the plates and are adapted to abut against each otherwhen the plates are brought together into operative position, andsecuring means engagingsaid flanges for holding the plates rigidlytogether on the culvert.

2. The combination with a corrugated metal culvert, of an abutmenttherefor, said abutment comprising a plurality of complementary platesconstructed to tit snugly into one of the corrugations of the culvert,the

contiguous edges of said plates being pro` are adapted to abut againsteach other when the plates are brought together into opera.- tiveposition, and securing means'engaging said flanges to hold the platerigidly together on the culvert.

3. The combination with a corrugatedmetal culvert, of an abutmenttherefor, said yabutment comprising a plurality of complementary latesconstructed of corrugated metal to t snugly into one of the corrugationsof the culvert, the contiguous edges of said plates` being provided withlateral ang'es Whichextend at right angles to the body of the plates andare adapted to abut .against each other when the plates are broughttogether into operative position, and' securing means engaging saidflanges to hold the plates rigidly together on the culvert.

et. The combination with a culvert, of an abutment therefor, saidabutment comprising a plurality of complementary plates of corrugatedAmetal constructed to t around the body of Athe culvert, the contiguousedges of said4 plates being provided with lateral flanges which extendat right angles to the body of the plates and are adapted to abutagainst each other when the plates are brought together into operativeposition, and securing means engaging said ianges to hold the platesrigidly together on the culvert.

5. The combination with a culvert, of an abutment therefor, saidabutment comprising a` plurality of complementary plates constructedofcorrugated metal to fit around into one ofthe'corrugations of theculvert,

lateral abutting flanges provided on the contiguous edges of said platesand running transversely to the corrugations on the plates, and securingmeans engaging said flanges to hold the plates rigidly together on theculvert. l 7 The combination With a culvert, of an abutment therefor,said abutment comprising a plurality of complementary platesconstructedto t around the body ofthe culvert, the contiguous edges of saidplatesbeing provided with lateral flanges which extend at right anglesto the body of the plates and are adapted to abut against eachother whenthe plates are brought together into operative position, and .boltspassing through said flanges for holding gether on the culvert.

8. The combination with a culvert, of an abutment therefor, saidabutment comprising a plurality ofcomplementary plates of corrugatedmetal constructed to it around the body of the culvert, thecontiguousedges of said plates `being provided with lateral ilangeswhich extend at right angles 4to the body of the plates and are adaptedto abut agalnst each' other When the plates are the plates rigidlytobrought together into operative position, and

bolts passing through said flanges to hold the plates rigidly togetheron the culvert.y
